i ran the three vtec wires i need from the ecu through to the motor where i just added pins to my plugs on my stock harness for the knock sensor and vtec solenoid but when came to doing the same with the oil pressure sensor there doesnt seem to be a place to put another pin. the engine harness came with the motor 99 b18c ITR JDM and im using the stock DX harness just adding the extra wires. any idea why this is??
